Source: Bang ShowbizMiranda Kerr used to be a tomboy and still finds climbing trees "rewarding". The Victoria's Secret beauty - who has 21-month-old son Flynn with her husband Orlando Bloom - was a tomboy when she was younger and still likes to indulge her adventurous side.She told the December issue of Esquire magazine: "I spent my childhood outdoors on my grandparents' farm. I learned to ride a motorbike when I was about six, a little PeeWee 50."I'd climb trees - there was a big weeping willow. We had a flying fox [a zip-line]. I was so fortunate to grow up like that."I really feel that my body craves to be in the mountains or by the ocean or in the countryside. I still like to climb the odd tree. Yeah, it's fun! I like to climb. I find it very rewarding. You feel like you're going somewhere. I don't like abseiling, though. I don't like going down. I like going up."However, Miranda, 29, admits she has had some mishaps with her climbing antics.The Australian model said: "It is tough! I got stuck up a tree when I was about seven, and my dad had to come and get the ladder to get me down. I loved to climb all the way up to the top. I must have been a koala in my past life."Miranda's full interview is in the new issue of Esquire, which goes on sale on Thursday (01.11.12).
